摘　　要：This work aimed at analyzing the petroleum adsorption capacity and the compressive strength of cellulose cryogels produced with the addition of 4 and 8%(w/w)sodium hydroxide(NaOH).Cryogels were produced from a 1.5%(m/m)suspension of cellulose microfibers,which originated from Pinus elliotti,in distilled water.The addition of NaOH increased the compression strength of cryogel by 30% when compared to cryogel without the reagent.Due to the 50% decrease in volume,the cryogel FLNB-8h(8%NaOH)has its petroleum adsorption capacity decreased in average by 58%,whereas the FLNB-4(4%NaOH)cryogel had it only by 14%.The cellulose suspension which provided the best results for the properties of the cryogels tested had a 4%concentration of NaOH.
